（Mirco Circuit Breaker 就是MCB，空气开关或者微断啦；Moulded Case Circuit Breaker 就是MCCB，塑壳断路器. TPN： 为三相+N的断路器， T指THREE 英文三的缩写， P 表示火线， N 零线。 一般也写成3P+N.

TP (Triple Pole) MCB: In Three Pole MCB, switching & protection is affected in only three phases and the neutral is not part of the MCB. 3 pole MCCB signifies for the connection of three wires for three phase system (R-Y-B Phase). Application: Three Phase Supply only (Without Neutral).

2013年6月24日 · As the name specifies TPN - Tripple pole isolation & neutral link is direct (no isolation) where as 4 pole MCB has 4 pole isolation. What is the correct technical difference betweenTPN and 4-POLE MCB? Thanks in advance. Madhan.

2021年9月22日 · TP ( Triple Pole) MCB: Only three phases of the circuit are switched and protected by a triple/three-phase micro circuit breaker, not the neutral. TPN (3P+N) MCB: A TPN MCB has switching and protection for all three phases of the circuit, and Neutral is also included as a separate pole.

2013年12月28日 · TP MCB is used in 3phase 4wire system. It is denoted as TP+N which will mean a three pole device with external neutral link which can be isolated if required. For the 4 pole breakers, protection applies to current flow through all poles. However when breaker trips or manually opened, all poles are disconnected.

2016年5月16日 · TP MCB is utilized as a part of 3phase 4wire framework. It is indicated as TP+N which will mean a three shaft gadget with outer unbiased connection which can be separated if required.
